Huffington Post: A new material has the ability to nearly instantly fill the holes made when it is suddenly punctured. Created by Timothy Scott of the University of Michigan in Ann Arbor, the material is made of a liquid resin sandwiched between two polymer sheets. When the sheets are punctured, the resin flows into the gap and hardens as it reacts with oxygen in the air. Although this isn't the first self-healing material, it is the quickest to repair itself. Such a self-repairing material would be extremely useful for spacecraft, which risk catastrophe when punctured by micrometeorites or space debris.
